hOi, Use the right and left arrow keys to navigate the song library. Press space to toggle if the current song is going to repeat or go to the next. You can see if it's repeating or not by moving your mouse over the project window. If you find a song you like, go to the sprite titled "Song Database," click on sounds, find your sound, open your backpack, and drag it in there. Tell me what your favorite song is in the comments, my favorite is #10
